EXPLANATION
The volume of a pyramid is given by the formula,
The base of the pyramid is an equilateral triangle.
The base area is
The volume of the pyramid is now equal to:
Answer:
The x coordinate of the parabola's vertex is: 5
Step-by-step explanation:
Although you didn't finish the phrases of the question, if they were asking the x-value for the x-coordinate of the parabola's vertex, which is a typical question for this type of problem, recall that the vertex is position equidistant from the parabola's branches because the parabola is a symmetric figure.
Therefore we need to find the point half way between x = 2 and x = 8.
Notice that the distance between these two points is "6" units, and half of such distance is "3" units, so the vertex must be located 3 units to the right of 2 (or equivalently 3 units to the left of 8).
Therefore, the x-coordinate of this parabola's vertex is "5"
The new mixture has a total volume of 5 L + 9 L = 14 L.
70% of the 5 L alcohol solution is alcohol, so that it contributed 3.5 L of alcohol to the mixture. The pure water contributed no alcohol. So in the mixture, the concentration of alcohol is
3.5 L / 14 L = 0.25, or 25%
